SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 666,069. dated January 15, 1901.

Application filed August 11, 1899- Serial No. '726,883- (No model.)

T0 all whom. it nfl/ay concern:

Be it known that I, MATTHEW SCHIER, a citizen of the United States, andfa resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Seal-Locks, of which the following is a specification.

My invention relates to improvements in car-seal locks. Its object is to provide a lock to be closed by a sliding bolt which simultaneously with locking the door locks within its case a seal which m ust be broken or mutilated before the lock can be opened, which may be quickly closed and opened, and which is adjustable to allow for shrinking and warping of the door.

Referring to the drawings, in which like parts are indicated by similar reference-letters wherever they occur throughout the various views, Figure l is a front View of the door of a freight-car with the lock embodying my invention attached thereto upon a small scale. Fig. 2 is a longitudinal vertical sectional view of the same in theclosed position, upon a greatly-enlarged scale, taken through line oc a: of Fig. 5. Fig. 3 is a similar view taken through line y y of Fig. 5. Fig. 4 is a front elevation of the lock in the closed position. Fig. 5 is a longitudinal horizontal sectional view taken through line 5 5, Fig. 3. Fig. 6 isan end elevation in the closed position, the dotted lines showing the case-lid thrown up. Fig. 7 is a transverse vertical sectional view taken through line 2 2 of Fig. 3. Fig. 8 is a transverse vertical sectional View of the keeper, taken through line .e z of Fig. 4f. Fig. 9 is an inverted plan view of the keeper,show ing a part of the bolt, the dotted lines showing the sliding roller for coupling the bolt and the keeper. Fig. 10 is a detail inverted plan View of the keeper with the lower bar thereof, the bolt, and the roller removed.

, Referring to the parts, the case A, which is to be secured near the edge of a door R, has ways a a upon its bottom to guide a sliding bolt B, which enters the case through an opening a? in its end a3. The lid consists of a rectangular frame hinged to the case and having brackets a5 and a6 projecting from its under side, which when the lid is closed pass down through slots ct" and as, which are made in the bottom of the casein alinement with the ways a and a'. The sliding bolt passes through these brackets and holds the lid closed. The bolt has its upper edge cut off at the forward end to form an incline b to raise the loose dog b and a slot b2 back of the incline, into which the dog drops to lock the bolt within the case. The downward motion of the dog is limited 4by lugs b3 b4 striking the tops of the Vertical ways a9 am.

Covering the ways a and a', a9 and all), and the bolt B is a plate a, which has a small slot @12 in its upper edge, as shown in Fig. 3, through which the linger or an implement may be passed to disengage the dog b from the slot b2 to allow the withdrawal of the bolt from the case. Upon the plate a a seal C is placed before the lid is closed, so as to cover the slot am and the dog b and be locked within the case when the lid is closed and the bolt B pushed into place. The seal is made of glass or other frangible material, which must be broken before the dog may be reached to release it from the bolt.

Immediately beneath the seal, if it be made of transparent material, a card D is placed containing the destination of the contents of the car, dto., or such data may be steneiled upon the inside of the seal, or if it be nontransparent such data may be indicated upon the exterior.

The keeper E, which is to be secured to the jamb R or to an abutting door, and the bolt B are coupled together by a roller e, which engages a central slot b5 in the bolt. The ends of the roller e are reduced to form an upper journal e' and a lower one e2. The upper one is to slide ina groove e3, formed upon the interior of the keeper. The lower one slides in the slot` e4 in the bar e5, which has tongues e6 and e7 to tit into grooves in the base e8 and e9 of the keeper. By this construction the bolt has a vertical adjustment in the keeper to compensate for a warping or shrinking in the door R, which would bring the case A higher or lower than the keeper. The bolt B being coupled to the keeper in the manner shown, when the frangible seal is broken and the dog b' elevated, as shown in dotted line, Fig. 2, to release it, it may be withdrawn until the wall of the slot b5 near its inner IOO end strikes the journal e2, at which time the end of the bolt is passed out of the case into the keeper, the door may be opened, and the bolt will swing down and be retained in' place until a new seal has been applied and the car-door closed, the cover of the lock-case closed and the bolt shoved to the closed position and locked by the gravitatin g dog b. Ordinarily the weight of the dogging-detent b will be sufcient to keep the bolt in the closed position; but if further security is required a spring might be employed to bear against the upper edge of the case and top of the dogging-bolt.

What I claim isl. In a seal-lock the combination of the lockcase adapted to be secured to the locking edge of the car-door, a keeper to be secured to the jamb opposite the lock-case the said lock-case having ways to receive a sliding bolt passing` through the keeper, a dogging-detent to rei tain the bolt in position, the bolt having its inner end beveled to throw up the doggingdetent when the lock is to be closed and having its upper edge notched to permit the dog to drop in and retain the bolt in the locked position, the notched lock-cover having inwardly-projecting perforated flanges to pass the bolt and lock the cover and the frangible seal held therein to preclude the opening of the lock and release of its bolt until the seal is broken, substantially as shown and described.

2. In a seal-lock the combination of the lockcase slotted at its forward end having a hinged cover adapted to receive a frangible seal and inwardlyprojecting brackets or ianges slotted to pass the bolt when the cover is closed, the locking bolt longitudinally slotted having its inner end beveled to throw up a locking-dog when the bolt is pushed to the locked position and its upper edge notched l l to receive the dog or detent, the gravitating dog guided in ways in the lock-case to be thrown up by the bolt when it is pushed to the closed position and dropped to prevent the retraction of the bolt when the notch in the bolt comes vertically below it, a keeper having its lower and upper plate grooved and a friction-roller having its journals tting the upper and lower grooves in the keeper and passing through the bolt -to permit the bolt to slide up or down in the keeper to compensate for warping or shrinkage of the door and case of the car and also coupling the bolt to the keeper when retracted to permit the opening of the door after the seal is broken, substantially as hereinbeforeset forth.

3. In a seal-lock the combination of the case having ways to guide a locking-bolt,a dogging-detent for the bolt and one end slotted to receive the bolt, a hinged cover having down wardly-projecting flanges or brackets at each end, said brackets being slotted to pass the bolt and the forward or edge end registering with the slot in the end of the lockcase to hold said cover closed and havingits top open, a transparent frangible seal held below the opening of the cover-top, a sliding bolt guided in ways in the case having its inner upper edge beveled to throw up a gravitating dog for locking the bolt in position, a notch to receive said gravitating dog and the keeper having an enlarged opening to permit the bolt to slide up or down therein to compensate for warping or shrinkage of the door or car-body, and means such as shown to couple the bolt to the keeper, substantially as'shown and described.
